*  DO NOT include this file directly.  This file is include after

*
*  There are several levels of strictness, each level includes the behavior of
*  all previous levels.
*
*  0 - Disable strict checking 
*  1 - Break on unapproved macros and misuse of statement 
*      macros such as __fallthrough (default)
*  2 - Deprecated some old macros that should not be used
*  3 - Use VS 2005 Source Annotation to make sure every macro 
*      is used in the right context. For example placing __in on a return 
*      parameter will result in an error.

*  Introduction
*
*  specstrings.h provides a set of annotations to describe how a function uses
*  its parameters - the assumptions it makes about them, and the guarantees it
*  makes upon finishing.
* 
*  Annotations must be placed before a function parameter's type or its return
*  type. There are two basic classes of common annotations buffer annotations
*  and advanced annotations.  Buffer annotations describe how functions use
*  their pointer parameters, and advanced annotations either describe
*  complex/unusual buffer behavior, or provide additional information about a
*  parameter that is not otherwise expressible.
* 
*  Buffer Annotations
* 
*  The most important annotations in SpecStrings.h provide a consistent way to
*  annotate buffer parameters or return values for a function. Each of these
*  annotations describes a single buffer (which could be a string, a
*  fixed-length or variable-length array, or just a pointer) that the function
*  interacts with: where it is, how large it is, how much is initialized, and
*  what the function does with it.
* 
*  The appropriate macro for a given buffer can be constructed using the table
*  below.  Just pick the appropriate values from each category, and combine
*  them together with a leading underscore. Some combinations of values do not
*  make sense as buffer annotations. Only meaningful annotations can be added
*  to your code; for a list of these, see the buffer annotation definitions
*  section.
* 
*  Only a single buffer annotation should be used for each parameter.

*
*  Note: "<>" represents the empty string.
* 
*  Level: Describes the buffer pointer's level of indirection from the
*  parameter or return value 'p'.
* 
*  <>         : p is the buffer pointer.
*  _deref     : *p is the buffer pointer. p must not be NULL.
*  _deref_opt : *p may be the buffer pointer. p may be NULL, in which case the 
*               rest of the annotation is ignored.
* 
*  Usage: Describes how the function uses the buffer.
* 
*  <> : The buffer is not accessed. If used on the return value or with
*  _deref, the function will provide the buffer, and it will be uninitialized
*  at exit.  Otherwise, the caller must provide the buffer. This should only
*  be used for alloc and free functions.
*
*  _in : The function will only read from the buffer. The caller must provide
*  the buffer and initialize it.
*
*  _out : The function will only write to the buffer. If used on the return
*  value or with _deref, the function will provide the buffer and initialize
*  it.  Otherwise, the caller must provide the buffer, and the function will
*  initialize it.
*
*  _inout : The function may freely read from and write to the buffer. The
*  caller must provide the buffer and initialize it. If used with _deref, the
*  buffer may be reallocated by the function.
*
*  Size: Describes the total size of the buffer. This may be less than the
*  space actually allocated for the buffer, in which case it describes the
*  accessible amount.
* 
*  <> : No buffer size is given. If the type specifies the buffer size (such
*  as with LPSTR and LPWSTR), that amount is used. Otherwise, the buffer is
*  one element long. Must be used with _in, _out, or _inout.
*
*  _ecount : The buffer size is an explicit element count.
*
*  _bcount : The buffer size is an explicit byte count.
* 
*  Output: Describes how much of the buffer will be initialized by the
*  function. For _inout buffers, this also describes how much is initialized
*  at entry. Omit this category for _in buffers; they must be fully
*  initialized by the caller.
* 
*  <> : The type specifies how much is initialized. For instance, a function
*  initializing an LPWSTR must NULL-terminate the string.
*
*  _full : The function initializes the entire buffer.
*
*  _part : The function initializes part of the buffer, and explicitly
*  indicates how much.
* 
*  Optional: Describes if the buffer itself is optional.
* 
*  <>   : The pointer to the buffer must not be NULL.
*
*  _opt : The pointer to the buffer might be NULL. It will be checked before
*  being dereferenced.
* 
*  Parameters: Gives explicit counts for the size and length of the buffer.
* 
*  <> : There is no explicit count. Use when neither _ecount nor _bcount is
*  used.
*
*  (size) : Only the buffer's total size is given. Use with _ecount or _bcount
*  but not _part.
*
*  (size,length) : The buffer's total size and initialized length are
*  given. Use with _ecount_part and _bcount_part.

*  LWSTDAPI_(BOOL) StrToIntExA(
*      LPCSTR pszString,  //  No annotation required, const implies __in.
*      DWORD dwFlags,
*      __out int *piRet   // A pointer whose dereference will be filled in.
*  );
* 
*  void MyPaintingFunction(
*      __in HWND hwndControl,     //  An initialized read-only parameter.
*      __in_opt HDC hdcOptional,  //  An initialized read-only parameter that 
*                                 //  might be NULL.
*      __inout IPropertyStore *ppsStore // An initialized parameter that 
*                                       // may be freely used and modified.
*  );
* 
*  LWSTDAPI_(BOOL) PathCompactPathExA(
*      __out_ecount(cchMax) LPSTR pszOut, //  A string buffer with cch elements
*                                         //  that will be '\0' terminated 
*                                         //  on exit.
*      LPCSTR pszSrc,                     //  No annotation required, 
*                                         //  const implies __in.
*      UINT cchMax,                              
*      DWORD dwFlags
*  );
* 
*  HRESULT SHLocalAllocBytes(
*      size_t cb,
*      __deref_bcount(cb) T **ppv //  A pointer whose dereference will be set
*                                 //  to an uninitialized buffer with cb bytes.
*  );
* 
*  __inout_bcount_full(cb) : A buffer with cb elements that is fully
*  initialized at entry and exit, and may be written to by this function.
* 
*  __out_ecount_part(count, *countOut) : A buffer with count elements that
*  will be partially initialized by this function. The function indicates how
*  much it initialized by setting *countOut.

/************************************************************************
*  Advanced Annotations
* 
*  Advanced annotations describe behavior that is not expressible with the
*  regular buffer macros. These may be used either to annotate buffer
*  parameters that involve complex or conditional behavior, or to enrich
*  existing annotations with additional information.
* 
*  __success(expr) T f() : <expr> indicates whether function f succeeded or
*  not. If <expr> is true at exit, all the function's guarantees (as given
*  by other annotations) must hold. If <expr> is false at exit, the caller
*  should not expect any of the function's guarantees to hold. If not used,
*  the function must always satisfy its guarantees. Added automatically to
*  functions that indicate success in standard ways, such as by returning an
*  HRESULT.
* 
*  __out_awcount(expr, size) T *p : Pointer p is a buffer whose size may be
*  given in either bytes or elements. If <expr> is true, this acts like
*  __out_bcount. If <expr> is false, this acts like __out_ecount. This
*  should only be used to annotate old APIs.
* 
*  __in_awcount(expr, size) T* p : Pointer p is a buffer whose size may be given
*  in either bytes or elements. If <expr> is true, this acts like
*  __in_bcount. If <expr> is false, this acts like __in_ecount. This should
*  only be used to annotate old APIs.
* 
*  __nullterminated T* p : Pointer p is a buffer that may be read or written
*  up to and including the first '\0' character or pointer. May be used on
*  typedefs, which marks valid (properly initialized) instances of that type
*  as being null-terminated.
* 
*  __nullnullterminated T* p : Pointer p is a buffer that may be read or
*  written up to and including the first sequence of two '\0' characters or
*  pointers. May be used on typedefs, which marks valid instances of that
*  type as being double-null terminated.
* 
*  __reserved T v : Value v must be 0/NULL, reserved for future use.
* 
*  __checkReturn T f(); : Return value of f must not be ignored by callers
*  of this function.
* 
*  __typefix(ctype) T v : Value v should be treated as an instance of ctype,
*  rather than its declared type when considering validity.
* 
*  __override T f(); : Specify C#-style 'override' behaviour for overriding
*  virtual methods.
* 
*  __callback T f(); : Function f can be used as a function pointer.
* 
*  __format_string T p : Pointer p is a string that contains % markers in
*  the style of printf.
* 
*  __blocksOn(resource) f(); : Function f blocks on the resource 'resource'.
* 
*  __fallthrough : Annotates switch statement labels where fall-through is
*  desired, to distinguish from forgotten break statements.
* 
*  __range(low_bnd, up_bnd) int f(): The return from the function "f" must
*  be in the inclusive numeric range [low_bnd, up_bnd].
*
*  __in_range(low_bnd, up_bnd) int i : Precondition that integer i must be
*  in the inclusive numeric range [low_bnd, up_bnd].
* 
*  __out_range(low_bnd, up_bnd) int i : Postcondition that integer i must be
*  in the inclusive numeric range [low_bnd, up_bnd].
* 
*  __deref_in_range(low_bnd, up_bnd) int* pi : Precondition that integer *pi
*  must be in the inclusive numeric range [low_bnd, up_bnd].
*
*  __deref_out_range(low_bnd, up_bnd) int* pi : Postcondition that integer
*  *pi must be in the inclusive numeric range [low_bnd, up_bnd].
*
*  __deref_inout_range(low_bnd, up_bnd) int* pi : Invariant that the integer
*  *pi must be in the inclusive numeric range [low_bnd, up_bnd].
*
*  The first argument of a range macro may also be a C relational operator
*  (<,>,!=, ==, <=, >=).
*  
*  __range(rel_op, j) int f(): Postcondition that "f() rel_op j" must be
*  true.  Note that j may be a expression known only at runtime.
*
*  __in_range(rel_op, j) int i : Precondition that "i rel_op j" must be
*  true.  Note that j may be a expression known only at runtime.
* 
*  __out_range(rel_op, j) int i : Postcondition that integer "i rel_op j"
*  must be true.  Note that j may be a expression known only at runtime.
* 
*  __deref_in_range(rel_op, j) int *pi : Precondition that "*pi rel_op j"
*  must be true.  Note that j may be a expression known only at runtime.
*
*  __deref_out_range(rel_op, j) int *pi : Postcondition that "*pi rel_op j"
*  must be true.  Note that j may be a expression known only at runtime.
*
*  __deref_inout_range(rel_op, j) int *pi : Invariant that "*pi rel_op j"
*  must be true.  Note that j may be a expression known only at runtime.
*
*  __range_max(a, b) int f(): Postcondition f acts as 'max', returns larger
*  of a and b.  Note that a and b may be expressions known only at runtime.
*
*  __range_min(a, b) int f(): Postcondition f acts as 'min', returns smaller
*  of a and b.  Note that a and b may be expressions known only at runtime.
*
*  __in_bound int i : Precondition that integer i must be bound, but the
*  exact range can't be specified at compile time.  __in_range should be
*  used if the range can be explicitly stated.
*
*  __out_bound int i : Postcondition that integer i must be bound, but the
*  exact range can't be specified at compile time.  __out_range should be
*  used if the range can be explicitly stated.
* 
*  __deref_out_bound int pi : Postcondition that integer *pi must be bound,
*  but the exact range can't be specified at compile time.
*  __deref_out_range should be used if the range can be explicitly stated.
* 
*  __assume_bound(expr); : Assume that the expression is bound to some known
*  range. This can be used to suppress integer overflow warnings on integral
*  expressions that are known to be bound due to reasons not explicit in the
*  code. Use as a statement in the body of a function.
*
*  __analysis_assume_nulltermianted(expr); : Assume that the expression is
*  a null terminated buffer. Use this to suppress tool noise specific to
*  nulltermination warnings, and capture deeper invariants tools can not
*  discover. 
* 
*  __allocator void f(): Function allocates memory using an integral size
*  argument
*
*  void myfree(__deallocate(Mem) void *p) : Memory is freed, no longer usable
*  upon return, and p may not be null.
*
*  void myfree(__deallocate_opt(Mem) void *p) : Memory is freed, no longer
*  usable upon return, and p may be null.
*
*  void free(__post_invalid void* x): Mark memory as untouchable when 
*  function returns.
*
*  ----------------------------------------------------------------------------
*  Advanced Annotation Examples
* 
*  __success(return == TRUE) LWSTDAPI_(BOOL) 
*  PathCanonicalizeA(__out_ecount(MAX_PATH) LPSTR pszBuf, LPCSTR pszPath);
*  //  pszBuf is only guaranteed to be null-terminated when TRUE is returned.

* Macros to classify fields of structures.
*                          Structure Annotations
*
*   The buffer annotations are a convenient way of describing
*   relationships between buffers and their size on a function by
*   function basis. Very often struct or class data members have similar
*   invariants, which can be expressed directly on the type.
*
*   Similar to our buffer annotations we can summarize all the various
*   structure annotations by one choosing an element from each column of
*   this table to build a composite annotation.
*
*           +--------------------------------------------------+
*           | Selector |  Units  |    Size/Init     | Optional |
*           |----------+---------+------------------+----------|
*           | __field  | _ecount | (size)           | empty    |
*           |----------+---------+------------------+----------|
*           | __struct | _bcount | _full(size)      | _opt     |
*           |----------+---------+------------------+----------|
*           |          | _xcount | _part(size,init) |          |
*           +--------------------------------------------------+
*
*   Note that empty represents the empty string. Sometime arguments need
*   to be "floated" to the left to give us a valid annotation name. For
*   example the naive combination __field_ecount(size)_opt is actually
*   written as __field_ecount_opt(size). Not all possible combinations
*   are currently supported or sensible. See specstrings_strict.h for
*   the currently supported set. Those that are supported are documented
*   below.
*
*Summary of Elements
*
*   Selector
*
*                __field
*                        The annotation should only be placed in front
*                        of data members of structures and classes. The
*                        data members are pointers to a block of data.
*                        The annotations describe properties about the
*                        size of the block of data. This can be used for
*
*                __struct
*                        The annotation should only be placed at the
*                        beginning of the definition of a structure or
*                        class. These annotations are used when a struct
*                        or class is used as a "header" that is
*                        allocated inline with a block of data and there
*                        is no apparent field that represents the tail
*                        end of the structure.
*
*   Units
*
*                _ecount
*                        All size and initialization values are in terms
*                        of elements of the appropriate type
*
*                _bcount
*                        All size and initialization values are in terms
*                        of raw byte sizes.
*
*                _xcount
*                        The size or initialization values cannot be
*                        properly expressed as a simple byte or element
*                        count, and instead a place holder is used to
*                        document the relationship.
*
*   Size/Init
*           All the size/init expressions can contain references to
*           other fields in the struct or class.
*
*                (size)
*                        The size of the buffer is determined by the
*                        expression size. Unless, the type of the buffer
*                        provides more information nothing is know about
